n this present work, we characterized the proteomes of pancreatic ductal adenocarcinoma (PDAC) cells and normal pancreatic duct cells by mass spectrometry using LTQ-Orbitrap, and identified more than 1200 proteins from each sample. On the basis of spectra count label-free quantification approach, we identified a large number of differentially expressed metabolic enzymes and proteins involved in cytoskeleton, cell adhesion, transport, transcription, translation, and cell proliferation as well. The data demonstrated that metabolic pathways were altered in PDAC, consistent with Warburg effect. Our analysis provides a potentially comprehensive picture of metabolism in PDAC, which may serve as the basis of new diagnostic and treatment of PDAC.

Abstract

n this present work, we characterized the proteomes of pancreatic ductal adenocarcinoma (PDAC) cells and normal pancreatic duct cells by mass spectrometry using LTQ-Orbitrap, and identified more than 1200 proteins from each sample. On the basis of spectra count label-free quantification approach, we identified a large number of differentially expressed metabolic enzymes and proteins involved in cytoskeleton, cell adhesion, transport, transcription, translation, and cell proliferation as well. The data demonstrated that metabolic pathways were altered in PDAC, consistent with Warburg effect. Our analysis provides a potentially comprehensive picture of metabolism in PDAC, which may serve as the basis of new diagnostic and treatment of PDAC.
